Hi, we’re deploying our devices behind a strictly controlled, firewalled network and the network team had asked us for the ports/hostnames we needed them to open for our Raspberry 3 devices running the latest version of balenaOS (managed via balenaCloud).
We gave them the following configuration (after going through balena network and security docs):
Hostnames: *.balena-cloud.com, *.docker.com, *.docker.io
Ports: UDP 53, UDP 123 and TCP 443
Direction: Unidirectional (from device to internet)
I can confirm that this access has been given. However, the device still doesn’t appear ‘Online’ on our balenaCloud dashboard.
The IT team has also informed us that the configuration we’ve given is not correct since the device is still making requests to other IP addresses and ports (one real IP it was making requests to: 188.8.131.52 being accesed by open VPN).
Can somebody from the balena team please provide an exhaustive list of ports/IP addresses my balenaCloud device will be accessing so I can pass on the same to our client’s network team?
